Are stars like Usain Bolt, Michael Phelps, and Serena Williams genetic freaks put on Earth to dominate their respective sports? Or are they simply normal people who overcame their biological limits through sheer force of will and obsessive training? In this controversial and engaging exploration of athletic success, Sports Illustrated senior writer David Epstein tackles the great nature vs. nurture debate and traces how far science has come in solving this great riddle.

50 Great Myths of Human Evolution uses common misconceptions to explore basic theory and research in human evolution and strengthen critical thinking skills for lay audiences, listeners, and students. Includes myths such as: "Humans lived at the same time as dinosaurs"; "Lucy was so small because she was a child"; "Our ancestors have always made fire"; and "There is a strong relationship between brain size and intelligence."

The most popular drug in America is a white powder. No, not that powder. This is caffeine in its most essential state. And Caffeinated reveals the little-known truth about this addictive, largely unregulated drug found in coffee, energy drinks, teas, colas, chocolate, and even pain relievers. Drawing on the latest research, Caffeinated brings us the inside perspective at the additive that Salt Sugar Fat overlooked.

Fifty years ago, neuroscientists thought that a mature brain was fixed like a fly in amber, unable to change. Today, we know that our brains and nervous systems change throughout our lifetimes. This concept of neuroplasticity has captured the imagination of a public eager for self-improvement - and has inspired countless Internet entrepreneurs who peddle dubious "brain training" games and apps. In this book, Moheb Costandi offers a concise and engaging overview of neuroplasticity for the general listener.

What happens when we accept that everything we feel and think stems not from an immaterial spirit but from electrical and chemical activity in our brains? In this thought-provoking narrative - drawn from professional expertise as well as personal life experiences - trailblazing neurophilosopher Patricia S. Churchland grounds the philosophy of mind in the essential ingredients of biology. She reflects with humor on how she came to harmonize science and philosophy, the mind and the brain, abstract ideals and daily life.

In this engaging account, renowned neuroscientist Giovanni Frazzetto blends cutting-edge scientific research with personal stories to reveal how our brains generate our emotions. He demonstrates that while modern science has expanded our knowledge, investigating art, literature, and philosophy is equally crucial to unraveling the brain’s secrets. What can a brain scan, or our reaction to a Caravaggio painting, reveal about the deep seat of guilt? Can ancient remedies fight sadness more effectively than antidepressants? What can writing poetry tell us about how joy works?

Every Wednesday, Gretchen Reynolds singlehandedly influences how millions of Americans work out. In her Phys Ed column for The New York Times, she debunks myths, spurs conversation, and creates arguments among her readers by questioning widely held beliefs about exercise. Expanding upon her popular columns, Reynolds tackles the questions we all have and (sometimes) ask about exercise.

Finally, the solution to the number-one reason we don't exercise: time. Everyone has one minute. A decade ago, Martin Gibala was a young researcher in the field of exercise physiology - with little time to exercise. That critical point in his career launched a passion for high-intensity interval training (HIIT), allowing him to stay in shape with just a few minutes of hard effort. It also prompted Gibala to conduct experiments that helped launch the exploding science of ultralow-volume exercise

How much control do we have over love? Much less than we like to think. All that mystery, all that poetry, all those complex behaviors surrounding human bonding leading to the most life-changing decisions we’ll ever make, are unconsciously driven by a few molecules in our brains.

Why do three out of four professional football players go bankrupt? How can illiterate jungle dwellers pass a test that tricks Harvard philosophers? And why do billionaires work so hard - only to give their hard-earned money away? When it comes to making decisions, the classic view is that humans are eminently rational. But growing evidence suggests instead that our choices are often irrational, biased, and occasionally even moronic. Which view is right - or is there another possibility?

In Arrival of the Fittest, renowned evolutionary biologist Andreas Wagner draws on over 15 years of research to present the missing piece in Darwin's theory. Using experimental and computational technologies that were heretofore unimagined, he has found that adaptations are not just driven by chance, but by a set of laws that allow nature to discover new molecules and mechanisms in a fraction of the time that random variation would take.

A leading brain scientist's look at the neurobiology of pleasure-and how pleasures can become addictions. Whether eating, taking drugs, engaging in sex, or doing good deeds, the pursuit of pleasure is a central drive of the human animal. In The Compass of Pleasure Johns Hopkins neuroscientist David J. Linden explains how pleasure affects us at the most fundamental level: in our brain.

To many, the brain is the seat of personal identity and autonomy. But the way we talk about the brain is often rooted more in mystical conceptions of the soul than in scientific fact.

What gives the human brain the creative ability that defines us all as individuals? Although the silicon version is hard on its heels, the brain remains the most remarkable computer in existence. Leading us through cognitive theory, neuroscience and Darwinian evolution with his trademark wit and wisdom, Michael Corballis explains what we know - and don't know - about our minds. How do we know if we’re really the top dogs in brain power?

Lydia Denworth presents insights from studies of everything from at-risk kids in Head Start to noisy cocktail party conversation, from songbirds to signal processing, and from the invention of the telephone to sign language. Weaving together tales from the centuries-long quest to develop the cochlear implant and simultaneous leaps in neuroscientific knowledge against a tumultuous backdrop of identity politics, I Can Hear You Whisper shows how sound sculpts our children’s brains and the life changing consequences of that delicate process.

Nearly every depressed person is assured by doctors, well-meaning friends and family, the media, and ubiquitous advertisements that the underlying problem is a chemical imbalance. Such a simple defect should be fixable, yet despite all of the resources that have been devoted to finding a pharmacological solution, depression remains stubbornly widespread. Why are we losing this fight?

The Pleistocene is the epoch of geologic time closest to our own. It’s a time of ice ages, global migrations, and mass extinctions - of woolly rhinos, mammoths, giant ground sloths, and not least early species of Homo. It’s the world that created ours. But outside that environmental story there exists a parallel narrative that describes how our ideas about the Pleistocene have emerged.

Is the end of HIV upon us? Award-winning research scientist and HIV fellow at the Ragon Institute, Nathalia Holt, reveals the science behind the discovery of a functional cure and what it means for the millions affected by HIV and the history of the AIDS pandemic. Two men, known in medical journals as the Berlin Patients, revealed answers to a functional cure for HIV. Their cures came 12 years apart, the first in 1996 and the second in 2008.

In Faster, Higher, Stronger, veteran journalist Mark McClusky brings listeners behind the scenes with a new generation of athletes, coaches, and scientists whose accomplishments are changing our understanding of human physical achievement and completely redefining the limits of the human body.

A deeply panoramic tour of the night, from its brightest spots to the darkest skies we have left. A starry night is one of nature's most magical wonders. Yet in our artificially lit world, three-quarters of Americans' eyes never switch to night vision and most of us no longer experience true darkness. In The End of Night, Paul Bogard restores our awareness of the spectacularly primal, wildly dark night sky and how it has influenced the human experience across everything from science to art.
